2007-2013 Chevrolet Silverado and GMC Sierra Crew Cab

2007 • 2008 • 2009 • 2010 • 2011 • 2012 • 2013

After a long, beautiful career touring the East Coast from Boston to Atlanta as a professional guitarist (Skip Castro Band, The Believers), I got my first full-time job at Crutchfield, where they actually pay me to write about one of my favorite subjects — car audio gear! It's now my mission in life to make people understand how much fun it is to have a first-rate sound system in your vehicle.

In a nutshell: This article is an overview of your truck's audio system and its upgrade options. Use our vehicle selector to find the gear that will fit your Silverado or Sierra.

Overview of the Chevy Silverado and GMC Sierra

Pickups aren’t just about hauling what’s in the bed or on the hitch anymore. They now feature interior touches that rival some luxury cars. The audio/video equipment in this new breed of pickup truck is no exception, and Chevrolet made sure to equip the new-for-2007 Silverado/Sierra Crew Cab 1500/2500 with some top notch features.

If you didn’t get the premium stereo on your truck, or you just want to improve on what’s already there, you can add anything from a simple speaker upgrade to a complete mobile theater makeover.

The chassis discussed here, known inside GM as the GMT900 and to the rest of the world as the Chevy Silverado and GMC Sierra, was introduced in 2007 (it's sometimes referred to as the "2007.5 Chevy Silverado").

The previous generation, the GMT800, hung around for another year as the "Classic" model. If you're not sure which '07 version you have, compare your truck to the photos above. The more aggressive-looking "Classic" features distinct "eyebrows" above the headlamps, plus a slight dip in the front bumper to accommodate the grille.

Factory stereo system in the Silverado/Sierra

These trucks came equipped with several stereo systems, including a 6 CD in-dash Bose® system and options to add navigation, rear seat audio, DVD systems, or satellite radio. It’s possible to add to or completely replace any of these stereo systems fairly easily, though getting to the amplifier and 6-1/2" subwoofer of the Bose system requires some extensive tear down of the interior. And it’s not hard to replace any of the features you may lose by taking out the factory stereo, because there are adapters that let you keep OnStar®, steering wheel controls, Bluetooth® and more.

You'll need a mounting kit to trim out the new radio, along with an antenna adapter that allows you to connect the Chevy antenna plug to your new radio. You'll get these parts at a deep discount with your receiver order, along with free step-by-step instructions for your Silverado. We also offer a big discount on the special adapters (see below) that you'll need for this installation.

Replacing your factory radio

These are reasonably easy systems to work with, but there are some differences between the regular and Bose systems. We want to give you a heads up now, but don't stress too much about the details. When the time comes for a new one, our Crutchfield MasterSheet instructions will tell you exactly how to install an aftermarket stereo in your Silverado or Sierra, no matter which version you have.

Standard system

If you’re replacing your standard GM radio, you’ll need to purchase an adapter that allows you to install a new stereo and still retain your warning chimes (along with OnStar functionality if you have it). You’ll also need a relay to keep your audible turn signals working with your new car stereo.

Bose system

If you’re replacing your GM Bose radio, you’ll need to buy an adapter to install your new stereo, allowing you to retain your warning chimes, the use of the Bose amplifier, and your OnStar functionality (if you have it). Another note: if you have the GM Rear Seat Entertainment (RSE) system, you also need a separate adapter to keep that system working and connect it to the audio/video output on your new receiver.

The Crutchfield website will make sure you get what you need for a proper installation. And if you have any questions about this stuff, our Advisors are just a phone call or chat session away.

Note: Some double-DIN radios may not fit because of irregularities in the dash substructure. It’s best to pick a double-DIN radio with wire harnesses or RCA connectors located on the bottom half of the back of the radio. Your other option is to pick a new radio with a depth that’s less than 6-1/2 inches.

Tools needed: Panel tool, 7mm socket and ratchet.

Detailed installation instructions

If you're looking for step-by-step instructions on how to install a car stereo or speakers in your car, there's nothing better than our exclusive Crutchfield MasterSheet™. This detailed, well-illustrated document is free with your Crutchfield order, or you can purchase one separately for $9.99.

Steering wheel audio controls

It's relatively easy to retain your truck's steering wheel audio controls when you install a new stereo. When you enter your vehicle information, our database will choose the adapter you need to make your factory steering wheel controls work with your aftermarket receiver.

Replacing the factory speakers in your Silverado/Sierra

The front doors will hold a variety of aftermarket speakers (Crutchfield Research Photo)

Removing the front and rear door speakers

Speaker replacement in the Silverado/Sierra is straightforward. The factory speakers in the front doors are closest in size to an aftermarket 6-3/4" speaker, but you’ll need an adapter plate to install any speaker in there. The front doors will accept several very common speaker sizes, including 6-3/4", 6-1/2", 5-1/4", and the adapter plates make for an easy installation. GM uses a 4-ohm speaker in the front doors, so you have lots of great choices.

In the Bose system, the speakes are low-impedance models, so you should replace them with low-impedance aftermarket speakers. A standard 4-ohm speaker will result in reduced volume.

You'll need speaker harnesses to attach your new speakers to the plugs that connect to the GM factory speakers. The speaker harnesses and speaker mounting brackets are included at a deep discount with every Crutchfield speaker order.

You can use the same size speakers in the rear doors. If you rarely have passengers in the rear seats, you might consider using these locations for midrange speakers that will really fill out your music’s sound. On the other hand, if you do a lot of people-hauling, you should consider replacing the rear door speakers with full-range units, which will maintain some high notes for back-seat passengers.

The Bose system includes A-pillar tweeters. (Crutchfield Research Photo)

Removing the front pillar speakers

The A-pillar tweeters found in some trucks are easy to remove, but you’ll need to do a bit of work to install the replacements. There's no wiring harness adapter made for this location, either, so you'll need a set of Posi-Products speaker connectors to hook everything up. You'll also need a mounting bracket, and using our universal backstraps will be a much easier solution than making one of your own. You can also use hot glue or silicone to secure your new tweeters.

Bass in your Silverado or Sierra

If your Silverado or Sierra came equipped with the Bose system, there is a small woofer mounted in the center console, along with the amplifier that powers all your factory Bose speakers. If you want more bass, it’s a good idea to simply eliminate or bypass this woofer and add a new, larger sub with a more powerful amp.

Thanks to a variety of custom enclosures that fit in the center console or under the rear seats, you’ll be able to keep valuable interior room and add more kick to your music and movies. To see the complete list of what's available, enter your truck's information in our Outfit My Car page.

A variety of sub enclosures will fit these trucks, including a dual 10" model that goes under the rear seat.

Other options for your Silverado or Sierra

There are plenty of other ways to improve your pickup. Here are a few suggestions:

Rear seat video

The optional DVD system features a flip-down screen in a roof console and two pairs of wireless headphones. A secondary set of controls for the radio and DVD system are housed in the rear of center console, and some models include an A/V input for adding more gear, like a gaming console. If you’re replacing the factory stereo, you’ll need an adapter to keep that system working and connect it to the audio/video output on your new receiver.

Adding an aftermarket DVD player and screens to a Silverado is pretty easy, thanks to products like flip-down overhead monitors with DVD players or replacement headrest screens that match the truck’s interior.

SiriusXM satellite radio

GM made satellite radio available as an option on most models. If you have a current subscription, you’ll want to add a new satellite radio tuner to your new head unit. You can call SiriusXM to move service over to the new stereo. If you have multiple vehicles, consider getting a plug-and-play tuner to take your satellite radio along, no matter which vehicle you’re driving.

Add a new amplifier for even better sound

The factory Bose system includes amps, but they aren’t ideal for use with aftermarket head units or speakers. It’s best to bypass or eliminate these amps in favor of newer gear if you want the best possible sound. You’ll find room for a new 4-channel amp in the spaces under and behind the seats or in the center console.

Truck security systems

Installing a security system in your Silverado or Sierra isn't easy (security systems rarely are), but it's definitely a good idea. Our Crutchfield Advisors can help figure out what you need to get the job done, but we usually recommend taking your car and new gear to a professional installer.

I have a 2003 Chevy Silverado 1500 LT with the bose speakers , i just want to change the headunit out but still keep the bose speakers but i would also like to keep the same power they have what should i do , i would replace the head unit with a touchscreen pioneer with Bluetooth so what should i do ?

Stacey, The 6-1/2" speakers up front will work nicely, but in the back, it's really up to you. Bigger can be better, but even a set of 5-1/4" speakers can fill out your sound nicely. You'll need to fabricate a mounting bracket for either size, though.

Titus, Cab designs are the same for the 2500 and 1500, so the 1500 speaker array should work fine. But we could do a better job of explaining that, so thanks for pointing it out!

The passenger side rear door speaker in my 2009 GMC Sierra crew cab quit working. I pulled the door panel and checked for continuity on the speaker, which indicated it was shot. I attempted to install a Rockford-Fosgate R165X3 as a replacement using the harness adapter Crutchfield provided and it sounds terrible (no bass).
I noticed that your guide indicates the impedance of the front & rear speakers as 4 ohms, but the speaker I pulled from the door has 8 ohms stamped on the magnet. According to Details section for the R165X3 speakers they are rated at 4 ohms. Would the difference in impedance (4 vs 8 ohm) cause the complete lack of low end sound from the new speakers?

I have a 2009 Chevy Silverado LTZ with a whining noIse coming through the stereo speakers. The pitch of the whine changes with the engine RPM. The stereo is factory. The noise stops when I turn the volume way down but the volume control does not control the volume of the whining noise. Could it be possible I have a bad amp?

I have a 2014 Silverado 2500 and I installed a JL Audio XD700/5 in place of the factory Bose amp, using the factory head unit signal wires. It was working fine for about 10 minutes of listening, but now there is no sound from any music source (AM/FM/XM/Aux) However, warning chimes, turn signals, NAV instructions, and bluetooth telephone all still work perfectly. I have no idea what happened, it is almost as if something switched inside the head unit. Any experience with this??

I just finished putting...well starting on mine I luckily didn't have the Bose system so tear down was simple we pulled the back seat's out and put a 1,400 watt amp in with a ported box under the seat with 2 10's and oh my does it beat and will even more so due to me adding a stinger battery so my lights will stop dimming....after Christmas my plan is to pull the back seat again and do another amp there and wire my mids and highs from there
1 day at a time I guess but thank you for the speaker sizes man that's going to make my life much easier

Why does the radio/cd player sounds low and the volume will not adjust. Once the radio/CD is turned off for awhile the speakers sounds are normal and adjustments return to normal?/.
